Product details

The STM32F105VCT6W: The ARM Cortex-M3 core runs at 72 MHz.

256 KB of program Flash and 64 KB of SRAM (64K x 8).

USB OTG and CAN — connectivity without an external PHY

Includes USB OTG full-speed and CAN 2.0B controller.

80 I/O and 100-LQFP — footprint and routing

80 I/O lines in a 100-pin LQFP (14x14 mm body).

For dual-sourcing resilience, the STM32L151CBU6A shares the same Cortex-M3 core and peripheral set but runs at 32 MHz and targets low-power applications — it is not a pin-compatible drop-in, but a functional alternative for designs that can trade speed for battery life.

Frequently asked questions

How does STM32F105VCT6W compare to STM32F105VCT6?

The STM32F105VCT6W and STM32F105VCT6 share the same core, memory, and peripheral set. The 'W' suffix indicates a different ordering code variant — functionally identical, but verify the specific package and temperature grade against your BOM before substituting.
